With my old PVR, I could use the swap to see which two channels were on the tuners and skip back to begin watching. Are the tuners in the gateway always on? And if so, can I see what channels they are on and skip back to begin watching?
The Tuners are always on, and if all are in use as long as you know the channel you will have access to the buffer.
That being said, there is no dashboard or menu that exposes the tuners (in a friendly manor). In the installer menu for those that know how to get into it, there is a tuner Status menu under "Diagnostics" that shows what active channel is set on each tuner, but I wouldn't call that a preferred approach. Ideally a menu with easy access is preferred and we have a feature request noted for that already.
Morning hijikibc, there's no real way find out what tuners are tuned to what channel on the fly like that as far as I know, especially when you add in factors such as what might be recording at the moment and multiple Portals making multiple requests.
I'm sure (Gateway overlord) mark_vse can give you a more thorough technical response on that, so I'll tag him here for you.
